After reading the thread of air powered grease guns, this was brought to mind. I'm thinking of purchasing a rechargable impact gun for changing my blades. After seeing a service tech at my local dealer do it, I knew this was the way to go. Fast! The gun he had was a Snap-on, but I understand Milwaukee makes a less expensive one. I have an air and electric one (handy) but I figure this I could carry in my tool chest on the trailer. Do any of you guys have one of these rechargables?
